UNITED STATES WILLIAM M. SHAW, OF GREENVILLE, MAINE.

SASH LOCK OB FASTENEB.

To all whom it may concern:

Be it known that I, WILLiAM M. SHAW, a citizen of the United States, and a resident of Greenville, in the county of Piscataquis and State of Maine, have made a certain Invention Relating to Sash Locks or Fasteners, of which the following is a specification.

This invention relates to fastening devices and has particular application to a device especially useful for fastening windows, doors, transoms, and the like.

The invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claims.

In the accompanying drawings, by way of illustration, I have shown my invention as employed in connection with a window, but I wish it to be understood that I do not limit myself to this precise use, nor to the precise construction shown, as modification and variation may be made without departing from the spirit of the invention or the scope of the claims.

Referring to the accompanying drawings in detail, Figure 1 is a vertical,sectional view taken through a window casing and windows showing my invention applied thereto; Fig. 2 is also a detail view showing a portion of the rod and the top fastening disk in elevation and the other locking disks of the device in section; Fig. 3 is a top plan view of one of the disks adapted normally to be maintained in its stationary position, as is shown by the screws passing therethrough; Fig. 4 is a top lan view of the interior disk and showing its ocation relative to the stationary disk; Fig. 5 is a side view showing the relative location of the various disks of the fastening when in locking position; Fig. 6 is a top plan view of a modified form of the locking device; Fig. 7 is a side view, and Figs. 8 and 9 are views showing the intermediate locking disk in position to hold, in a raised position, a window unprovided with weights or springs.

With the use of my invention such as will be hereinafter described more in detail, I attain several important ends. For instance, referring especially to the application of the same as a window lock and support, either one of the sashes of a window,such as the upper or lower sash, may be raised or lowered to any extent desired and locked in such raised or lowered position, so that it will be impos- Specification of Letters Patent.

Application filed June 7, 1907.

Patented June 15, 1909.

Serial No. 377,684.

I sible to move the window without first trip- 1 ping the locking device.

I will now proceed to describe the invention as shown in the accompanying drawings, that is to say, as applied to a window.

Referring now to the accompanying drawings in detail, A indicates the ordinary window-casing, B the lower sash thereof, and C the upper sash.

At any suitable point, preferably to the upper sash, I secure a bracket 5 to which is connected the rod 6, such rod being of any suitable length and in case of a window fas tening, a length preferably a little longer than one of the window sashes. To any suitable point on the adjacent sash, in the present instance, the lower sash, I have permanently secured a suitable member 7 which is preferably in the form of a disk, such memher being secured by a screw 8, or other means, and has an opening 9 thereinfor the passage of the rod 6. A locking member preferably also in the form of a disk, indicated by the numeral 12, is formed with an opening 18 for the passage of the rod and rests upon the top of the lower disk. This intermediate disk is provided with a slot 14 of sufiicient size to fit the shouldered or shank portion of the locking lug 10. I also provide a top member 13 also preferably in the form of a disk, loosely mounted upon the rod 6, this disk 13 having an aperture 14 therein, for the passage of the rod.

The operation of the device shown in Figs. 1 to 5 inclusive is as follows: If the window be one unprovided with weights or springs, the lower sash may be raised any desired distance and locked in such elevated position by lifting the outer edge of the intermediate washer, so that it bites or frictionally engages with the rod and the weight of the window resting upon the same will hold it in such locked position. By simply tilting or tripping the intermediate disk the window may be lowered. If it be desired to lower the upfor instance, for the purpose of admitting air, such sash may be lowered the desired distance and the upper disk turned so that its edge rests upon the top of the lug on the stationary disk, as shown in Fig. 2. By this arrangement the upper window will be held locked against movement and may not be lowered farther, but may be closed by pushing the window upward. The effect of per sash,

the washers is to lock the two windows together so they may not be the upper sash and the lower edge of the bottom sash, but such windows may only be closed when the locking device is arranged. Where the windows are hung with cords and weights the top sash may be lowered for air and the top disk turned to rest on the lip, as before described.

By my arrangement of lock the windows are held firmly secured in a desired position and may be opened sufficiently to admit air tothe building, yet at the same time prevent the access of personsthrough the window.

In Figs. 6 and 7 I have shown a slightly modified form of fastener. In this case the upper disk 15 is provided with a slot 16 fitting beneath the shoulders 17 of the lug 18 formed on the stationary disk 19 secured to the lower sash. This lower disk is formed with a forward lip 20 upon which is adapted to rest'the lug or thumb plate 21 formed on the upper washer 15. To look the sashes together in the manner heretofore described it'is only necessary to tilt the upper washer as is shown in Fig. 7; that is to say, so that the thumb plate 21'rests upon the lug 20, with the slotted portion 16 of the top disk 15 fitting beneath the shouldered portion 17 of the lug 18. This is the normal position of the modified form of fastener, the sashes being at all times locked together-by reason of the dropping of the unsupported end of disk 15; when it is desired to lower or raise either or both of the sashes the thumb plate 21 is depressed bringing the disk 15 to a substan tially horizontal position permitting of the free movement of the rod through the disk.

\Vith my invention several advantageous ends are attained. It will benoted that I have provided a simple locking device which will enable the windows to be locked securely together, while one or the other, or, in some instances, both, of the sashes are raised or lowered a desired distance, sufficient to admit'air to the room, while preventing the access of persons thereto, and thus the device acts as a preventive of the admission of undesirable parties, such as sneak thieves, and the like.

As heretofore stated, I have shown the device as applied particularly to a window, but, of course, it is understood thatit may be used for numerous other purposes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v
